CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation of U.S. patent application Ser. No. 16/718,035, filed Dec. 17, 2019, which is a continuation of U.S. patent application Ser. No. 16/251,549, filed Jan. 18, 2019 (now abandoned), which is a continuation of U.S. patent application Ser. No. 15/838,111, filed on Dec. 11, 2017 (now abandoned), which is a continuation of U.S. patent application Ser. No. 14/461,356, filed on Aug. 15, 2014 (now U.S. Pat. No. 9,875,324), which claims priority pursuant to 35 U.S.C. § 119(e) to U.S. Provisional patent Application No. 61/866,915, filed on Aug. 16, 2013, the disclosures of all of which are incorporated herein by reference in their entireties.

FIELD

The subject matter described herein relates generally to a system, process and method for simulating traction power and control in transportation systems under design conditions and/or utilizing real-time data.

BACKGROUND

Management of complex electrical systems such as power delivery and management in the transportation sector requires analysis of a wide array of variables. Some variables may include physical properties unique to power delivery lines, stopping and starting power required to move large vehicles such as trolleys and buses, weather, line interruptions, and many others. Use of a discrete resource, namely a specific number of tracks, rails, etc. on which vehicles may move also requires management of complex timetables and budgeting for expected and unexpected delays in the system. Because physical movement of vehicles in the system constantly impacts and influences the electrical load being felt by different parts of the system, analysis may become quite complex and burdensome. To this point an integrated system which is able to catalog and utilize the vast number of variables used in complex transportation systems has not existed in a way that makes it convenient for users to model real world scenarios, run effective simulations, and predict future scenarios in an effective and time efficient manner.

SUMMARY

Provided herein are embodiments of a system and method of which simulates and/or monitors real-world conditions and operation and is able to use this data in order to simulate and predict future operational conditions. The system and method are also robust in that they do not require the shut down and testing of equipment but rather can be used during normal operation of the transportation system to be analyzed.

Other systems, devices, methods, features and advantages of the subject matter described herein will be or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, devices, methods, features and advantages be included within this description, be within the scope of the subject matter described herein, and be protected by the accompanying claims. In no way should the features of the example embodiments be construed as limiting the appended claims, absent express recitation of those features in the claims.

DETAILED DESCRIPTION

Before the present subject matter is described in detail, it is to be understood that this disclosure is not limited to the particular embodiments described, as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting, since the scope of the present disclosure will be limited only by the appended claims.

As used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural referents unless the context clearly dictates otherwise.

The publications discussed herein are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the present disclosure is not entitled to antedate such publication by virtue of prior disclosure. Further, the dates of publication provided may be different from the actual publication dates which may need to be independently confirmed.

Turning to FIG. 1A, an example embodiment of a data flow diagram in accordance with the present invention is shown.

FIG. 1A shows data flow diagram 1000 including input information 1002 regarding rolling stock 1004, infrastructure 1006, and timetable 1008 s. Input information is then sent to a simulation section 1010. Simulation section 1010 includes interactivity 1012, which can include typical video and simulation interaction tools such as play, pause, stop, fast-forward, rewind and others including playback sliders (shown further in FIG. 39), simulation program 1014 s, and animation 1016 s. Simulation section 1010 may then create output information 1018. Output information 1018 may include reports including diagram 1020 s, transportation graph 1022 s, occupation 1024 s (which can be graphs or other diagrams of which trains are located on which tracks and/or statistical representations of how many trains are on particular tracks and where at particular times), and statistic chart 1026 s.

FIG. 1B shows another example embodiment of a system. In the example embodiment third party signaling data (such as speed limits and others), train schedule information, track definition information (such as elevation, bends, environmental conditions and others) and rolling stock information (such as weight, length, aerodynamics and other train specific information) can be inputs to train performance calculations. Train performance calculations can then output load profiles as a function of time. Load profiles can also be understood as mechanical profiles. Load profiles can be used by electrical calculation block to determine what demand exists on the electrical side to meet the mechanical demands of the system. Traction power GUI (for both AC and DC current) may exchange information with both electrical calculation block and Real-time traction power management applications.

FIG. 1C shows another example embodiment of the system. In the example embodiment track information, rolling stock information, signaling and train schedule information as well as information from traction power GUI can be inputs to train performance. Additionally, train schedule information and signaling can communicate with each other. Train performance may send information to traction power GUI which can also exchange information from traction power management and electrical calculation block. Traction power management block can send information to electrical calculation block. Traction power GUI can output time domain performance calculation information.

FIG. 2 shows an example embodiment of data flow in the system. In the example embodiment, data imported into Geographic Information Systems (GIS) View 2002 may be synchronized into an electrical circuit representation in One Line View (OLV) 2006. OLV typically does not require a distribution network composite to be created.

In some embodiments GIS View can be associated with only one Associated OLV at a time. In many embodiments, associations can be changed since the only common component is the track and its included devices. Associated OLV's can be changed in some embodiments. In some embodiments GIS View can be associated with a plurality of OLV's at one time.

FIG. 3A shows an example embodiment of a GIS View 3000 with associated components in accordance with the present invention. In the example embodiment various components are shown including Isolator or insulator 3002 (which can be a break in an overhead wire), train 3003, substation 3004, Substation or switching station 3006, Station/platform 3008, Signal post 3010, Distance marker 3011, Speed post 3012, first speed 3014, first track 3016, second track 3018, second speed 3020 and others. In the example embodiment additional geographic details are also shown such as roads, parks, and other topographical features. Speed post 3012 may appear as a color coded track in OLV. Distance marker 3011 may be included on a per track basis and may show different units of measurement based on local custom (such as kilometers or miles) and in some embodiments may be toggled or switched between units of measurement as appropriate.

FIG. 3B shows an example embodiment of an OLV 3001 with the same associated components shown in FIG. 3A and how the components are represented when they appear in OLV in synchronization with FIG. 3A.

FIG. 3C shows another example embodiment of a GIS 3005 showing switching and other substations in accordance with the present invention.

In the example embodiment additional geographic details are also shown such as roads, parks, and other topographical features.

FIG. 3D shows an example embodiment of an OLV with the same associated components shown in FIG. 3C and how the components are represented in OLV.

FIG. 3E shows an example embodiment of a geospatial GIS View with a station and associated tracks in accordance with the present invention. In the example embodiment track 3044 is shown with no branches. Track 3046 is shown with Station-1 3040 at one end and Station-N 3042 at the other end. Track 3046 branches into subtrack 3052 with angle 3054 between track 3046 and subtrack 3052. Subtrack 3052 further branches into subtrack 3048 with angle 3050 between subtrack 3052 and subtrack 3048.

FIG. 3F shows an example embodiment of an OLV with the same associated track, subtrack, and angle components shown in FIG. 3E and how the components are represented in. In the example embodiment angles shown in OLV may not match exactly with those from GIS view, as shown in the example embodiment in FIG. 3E. Standardized angles such as the forty-five degree angles of 3054, 3050 can help user readability in OLV.

FIGS. 3G and 3H show an example embodiment of a side-by-side view of diagrams of tracks in GIS View and OLV respectively. FIGS. 3G and 3H are more complicated track branching areas than those shown in FIGS. 3E and 3F. Parallel tracks 3066, 3064, 3062, and 3060 are shown in each figure. Also shown are angle 3068 which represents the branching angle of track 3070. 3072 branches off 3074 which branches off 3070 and 3076 branches off 3074.

FIG. 4B shows an example embodiment of a graphical output.

FIG. 4C shows an example embodiment of a system architecture 4100 for implementing the systems and methods described herein. In the example embodiment one or more inputs/controllers 4102 can provide information to one or more servers 4104, accessible and updatable by one or more user consoles 4106 and third party servers 4108. In some embodiments real-time data can be captured by one or more inputs/controllers 4102 and sent to server 4104 for processing.

FIG. 4D shows an example embodiment of system component blocks and their interaction 4200. In the example embodiment system operating data 4204 (which can include real time data) is sent to modal analysis 4206 and electrical power system topology with subsystems 4208. Electrical database also sends data to 4208. 4208 sends data to predictive simulation 4212 and traction power analysis 4210. Traction power analysis 4210 exchanges data with 4212 and 4206 and receives data from 4208 in addition to exchanging information with knowledgebase 4214. Controller 4216 receives data from 4210.

Turning to FIG. 4E, a system component diagram 4300 is shown. In the example embodiment common database 4308 exchanges information with graphical user interface editors 4306, predictive simulation 4302, system configuration or topology 4304, and schematics 4310. Engineering libraries 4312 exchange data with graphical user interface editors 4306 and schematics 4310.

In the example embodiment computer models of electrical power systems are developed and maintained in a common data base. Computer systems are used to develop these operating virtual models of electrical systems via graphical editors and engineering libraries of common components. Separate data editors for Bus, Branch, and Machine data allow the user to model the system in a common database. User-edited libraries provide typical data which can be substituted into the database upon request. When predictive studies are to be performed, the system automatically extracts the necessary parameters from the common database.

FIG. 5A shows an example embodiment of a difference between GIS View and OLV in accordance with the present invention. In the example embodiment a user may not be able to add any components on a track 5002 in OLV. In many embodiments this will only be allowed in GIS View. In some embodiments in OLV connection of component 5004 s may only be allowed. In numerous embodiments drops may be allowed in both GIS and OLV. Likewise, in numerous embodiments connections may be allowed in both GIS and OLV.

FIG. 5B shows an example embodiment of a difference between OLV and GIS in accordance with the present invention. In the example embodiment no components may be connected from a distribution toolbar. However, in OLV, AC and Instrumentation Toolbar component 5004 s can be connected to a track 5002 at connection point 5006 s. In some embodiments, components may be connected from distribution toolbar. In some embodiments AC and Instrumentation Toolbar components may be connected to track by dropping them on the track.

FIG. 5C shows an example embodiment of how components added in OLV may not be visible in GIS. In the example embodiment when a user adds a component 5004 to a track 5002 in OLV the component will not appear on GIS view. In many embodiments, addition of components in GIS or OLV will cause them to appear in the other of GIS or OLV as well.

In many embodiments, substations will appear as polyline objects in GIS View. In OLV a corresponding polyline object will be available. In many embodiments all detailed electrical connections will be completed in OLV. In applications where bend radius of a track needs to be calculated, the calculation will occur in GIS View. Track editor in GIS View will allow definition of terrain information. At least one similarity exists between GIS View and OLV is that train animation will be displayed in each. In Line/Rail Warehouse track/line impedances will be included for tracks. The user can define information included in this embodiment in various embodiments. Information in GIS and OLV in many embodiments only needs to be inputted into the system once, as GIS and OLV share databases and the information stored in them.

In many embodiments GIS View will have interoperability allowing users to import track layout from GIS sources like OpenStreetMap owned by the OpenStreetMap Community and supported by the OpenStreetMap Foundation. In some embodiments this may be achieved through Extensible Markup Language (XML) and the imported track layout may also bring the background layer. In the system described herein, numerous layers may be used, and the background layer may be the bottom layer. In many embodiments this background or bottom layer is the map. In GIS View track components can appear graphically similar to an edge and can be a unique component class. In OLV a track component can depict bends and can be a pinless component. In many embodiments, all components dropped on the track component in OLV will be pinless such that they seamlessly connect with the track and show no visible connection points. In alternative embodiments pins can be seen and used by users, for instance in manipulating components.

The Map Extents field allows a user to input a first latitude and longitude for a first corner of a map and a second latitude and longitude in order to define two diagonal corners of the map. The user may then select a download button to download a map from the selected server of the selected dimensions. After a successful download the layers button is selectable by the user. As with many user interface boxes there are Help, Ok, and Close buttons.

FIG. 9C shows an example embodiment of how to import an OSM file by selecting the location of the .OSM file and entering a first and second latitude and longitude. In some embodiments the latitude and longitude fields may be automatically populated based on the extents available in the .OSM file. After the fields are populated a user may enter any number greater or less than the maximum extents calculated. As an example, a user may originally select an initial size, such as the size of “Orange County, Calif.”. Then a user may wish to decrease the size by selecting a size such as “Newport Beach, Calif.” which is a city in Orange County. This is typically done with longitude and latitude coordinates in the system, however, it can be done differently in different embodiments such as by using county and city names.

After selecting an import button, the program can display “File Selection” dialog with a pre-defined filter for the .OSM file. In some embodiments similar editors to that shown in FIG. 9C may be applicable for KML, SHP and other file formats. Selecting an import button may cause the predefined filters to be .KML, . SHP, or others, respectively. Once a file is successfully read the layers button can become active.

FIG. 9D shows an example embodiment of map boundary setting using a central point and distance fields from the center point in accordance with the present invention. In the example embodiment a user may be prompted to choose the boundary distances in a particular unit of measure from the central geographic location (“Choose the site map extents, in feet, from the centroid of the selected parcel”).

SHP files may be downloaded from websites such as http://www.diva-gis.org/gdata and http://www.maperuzin.com/free-world-country-arcgi s-maps-shapefi es.htm.

FIG. 9E shows an example embodiment of a geographic coordinate system mapping display with input fields in accordance with the present invention. In the example embodiment an origin may be set using X and Y coordinates as well as latitude coordinates including degrees, minutes and seconds and direction of North or South and longitude coordinates including degrees, minutes and seconds and direction of East or West.

FIG. 9F shows an example embodiment of a user's ability to change cache size in accordance with the present invention. In the example embodiment a user may clear a local cache when rendering tiles using a clear memory cache button. In an example embodiment a disk cache size may be up to 2000 MB although in other embodiments this may be greater or less.

FIG. 9G shows an example embodiment of a layer inputting window in accordance with the present invention. In the example embodiment the editor shown may be displayed for a user when a user selects a layers button. Included in the mapping tab may be fields for source layer and element. Source layer may include roads, railway, shape, ID, description, parks and lakes. Elements may include dropdown menus. Users may also select or unselect an option to convert tracks with spline/curve. Users may also select or unselect an option to transfer unmapped layers as background and use radio buttons to select options to transfer as background to a GIS view or transfer as background to OLV.

FIG. 10A shows an example embodiment of a background map theme manager including numerous selectable fields with headings in groups in accordance with the present invention. When an import button is selected by a user a GIS View may display imported data objects and background map layers. In an example embodiment four layers were read from a map file: railway, roads, parks, and lakes. For a background map a theme manager may be modified in an example embodiment as shown in FIG. 10A.

FIG. 10B shows an example embodiment of a theme manager for data objects placed on a track in accordance with the present invention.

FIGS. 11B-11D show an example embodiment of a connector-less track connectable at a junction or node, connecting the track at the junction or node, and then moving the track around the junction or node respectively in accordance with the present invention. In the example embodiment shown in FIG. 11B, track 11002 and track 11004 have endpoints which are in close proximity to each other. When two segments of track are in close proximity the program may display possible connection available element 11004 to signify to a user that the track segments may be joined at a location. FIG. 11C shows an example embodiment of how a connection may appear when a user touches track 11002 and track 11004 in the program and the program makes a connection at location 11008. In some embodiments where track 11002 and 11004 are straight, aligned or nearly aligned the tracks will join seamlessly. In some embodiments where track 11002 and 11004 form an angle when connected at location 11008 then a bend point may be created in the track. FIG. 11D shows an example embodiment of how tracks may be rotated about a bend point after being connected. In some embodiments, users may delete bend points using a simple process such as a keyboard shortcut or point and click option. Similarly, in some embodiments bend points may be easily added using a simple process such as a keyboard shortcut or a point and click option.

FIG. 11E shows an example embodiment of a user deleting or otherwise removing a bend point and the tracks being automatically merged in accordance with the present invention. In the example embodiment track 11002 and 11004 are connected at bend point 11008. Upon deletion of bend point 11008, tracks 11002 and 11004 may be merged and create a single track line segment 11010.

FIGS. 11F-H shows an example embodiment of changing a track from straight or bent to subsequently being curved/arced in accordance with the present invention. In the example embodiment a user may change orientation from straight or bent to curved using simple keystroke commands or opening menus and selecting an option. In the example embodiment segment 11002 is converted to segment 11014 using two adjustment points. For example, a first adjustment point 11012 may be connected to segment 11004. A second adjustment point may be located at the terminus of segment 11014. Once the adjustment points are placed a user can bend and curve segment 11014 between the adjustment points in order to achieve a desired curve.

FIG. 11I shows an example embodiment of node properties in accordance with the present invention. In the example embodiment properties such as identifiers, services, connections, groundings, bonds to rails, and coordinates may each have the listed associated properties.

Turning to FIG. 11J, an example of three different node types is shown. In the example embodiment a node with a circular halo and grounding symbol signifies that the node is bonded and grounded. A node with a grounding symbol means that the node is grounded. A node with a circular halo means that the node is bonded.

Turning to FIG. 11K, an example of a three rail system is shown with grounding for a rail while a return and catenary rail not grounded or bonded.

Turning to FIG. 11L, an example embodiment of a three rail system is shown with a rail grounded and a return bonded to the rail.

Turning to FIG. 11M, an example embodiment of a track node editor is shown. In the example embodiment a user may name the node with an identifier and include Nominal kV in an info field. In a voltage field a user may include % V, kV and angle for both initial and operating conditions. Also included is an equipment field including a tag number (#), name, description and priority (such as critical). Nodes may be classified in a classification field including by zone, area, and region. Revision data and condition are discussed elsewhere herein and will not be repeated here to save space. Node connection may include radio buttons allowing users to choose between options. Subfields include connection with “1 phase 2 W” and “1 phase 3 W”, bonding with bonded or unbonded and status with grounded or ungrounded. Also included is a voltage limit field with minimum, maximum and duration as well as a button for cycling.

Turning to FIG. 11N, an example embodiment of distance markers displayed on a track is shown. In the example embodiment distance markers may be turned on or off in a theme manager screen. Generally, distance markers are shown at fixed distances selected in a track editor. In some embodiments distance markers may be set at a default of every 0.25 km. In the example embodiment distance markers 11020, 11022, 11024, 11026 are shown on track 11002.

Turning to FIG. 11O, an example embodiment of a distance marker editor is shown which may be displayed when a user opens it by first selecting a distance marker. In the example embodiment the distance marker editor allows users to edit labels, scale, scale units, distance, and distance units in addition to choosing whether to show values in GIS View and/or as a tooltip. In the example embodiment scale and scale units are limited to 1 and pixels respectively. Distance may be a number from 0.1 to 999 with units of feet, meters, km, or miles. In the example embodiment distance markers are not adjustable, meaning that the distances set in the distance marker editor scale directly to distances shown in GIS and OLV. In other embodiments distance markers can be adjustable and moved by users to help with readability. In the example embodiment GIS View may show distance values as annotations. In some embodiments when a user hovers a cursor or other tool over a distance marker a distance value of the marker may be shown as a tooltip.

Regarding nodes, junctions and bend points, users may drop them anywhere on tracks. If a user has not selected a track then junctions may be dropped on any location on a track or within a close, predefined range near the track. When users select tracks prior to selecting junction point buttons on a toolbar then a “snap and glue” or “magnetic” behavior may be enabled. In these modes a cursor may automatically lock on to a selected track element. These modes may be used for other components that may be dropped on tracks as well. In connection modes information may be displayed at the tooltip. This information may include x, y location; latitude and longitude; distance from nearest station and station name with associated units of measure; distance from track end 1 including station name; and distance from track end 2 including station name.

Turning to FIG. 11P, an example embodiment of a track speed limit editor is shown. In the example embodiment track speed limits may exhibit magnetic behavior as described above. When a speed limit component is placed on a track the editor may be displayed for the user such that the user may edit many of the options. Track type and speed units may be dropdown menus with selectable options. Freight train and passenger train options may be turned on or off as appropriate and the value may also be changed for each.

Turning to FIGS. 11Q-R, an example of numerous class types and ANSI standard speed limits are shown for freight and passenger trains. Additionally or alternatively when IEC standard is used FIG. 11R may apply. Speed units may be a non-editable dropdown list of km/h or mph.

In some embodiments a checkbox may be selected for displaying a track speed limit for passenger trains as shown in FIG. 11S. In an example embodiment a location may be shown which is not a bend point but rather is the location of the speed limit. This point may be moved along the track as appropriate.

In some embodiments both passenger and freight trains speed limits may be displayed as shown in FIG. 11T. In FIG. 11T, passenger train speed limit 8002 may be displayed for track 8002 near freight train speed limit 8030. Also included may be a display of freight train speed limit over passenger train speed limit or its inverse (45/90 in the example embodiment). In many embodiments speed limit markers may indicate the beginning of a speed limit section while if no other speed limit markers are placed then a placed speed limit marker may be enforced along the length of an associated track and/or segment.

FIG. 11U shows an example embodiment of a platform 11034 that can be sized and scaled and even dragged along a track 11002 at a point 11032 in accordance with the present invention. In the example embodiment transparency, color, de-cluttering, and other options may be controlled by the platform layer in a GIS theme manager. Selecting a platform and opening a platform editor may result in a screen showing such as the example embodiment in FIG. 11V.

Turning to FIG. 11V, an example embodiment of a display editor for a platform in accordance with the present invention is shown. In the example embodiment a train station associated with the platform being edited is selectable from a dropdown menu. While train stations may have two platforms (A & B), if only one side is selected then the display shown in FIG. 11W is shown.

FIG. 11W shows a train station 11034 and associated track with a single platform configuration.

FIG. 11X shows a train station 11034 and associated track 11002 with a dual platform configuration.

Turning to FIG. 11Y-Z, an example embodiment of a traction substation/switching station is shown in accordance with the present invention in GIS View and OLV view respectively. In the example embodiment, when a traction substation is dropped anywhere on a GIS view it becomes associated with the nearest track. In many embodiments a traction substation/switching station is a polyline object that may be sized, scaled, and dragged along a track. Traction substation/switching stations may be converted to polyline textboxes in OLV and paced near tracks based on a scale used to convert objects from GIS View to OLV.

FIG. 11AA shows an example embodiment of an editor for a single throw switch in accordance with the present invention in OLV or GIS. In the example embodiment this may be a section insulator with a switch in the open position and when added in OLV will have the same or similar properties to a switch in the open position. It should be understood that editors including but not limited to that shown in FIG. 11AA can apply changes to all user views including GIS, OLV, three-line views, and other views. This aids in simplifying user interaction with the system, as it allows users to apply updates and changes to each view simultaneously across all views. The chance for human error and other inconsistencies is significantly reduced since numerous individual editors are not required for each view to perform the same operations as applied to each view.

FIG. 11AB is an example embodiment of an editor for a single throw switch in accordance with the present invention. In the example embodiment an insulated overlap may be a switch in an open position, which may also be a default position, and when added in OLV will have the same or similar properties to a switch in the open position. Insulated overlaps can occur at substations while overlaps can occur along track lines not at substations.

FIG. 11AC is an example embodiment of an isolator switch editor in accordance with the present invention. In the example embodiment an isolator switch is a switch with open and closed position options. In OLV an isolator may have the same properties as a switch in closed position as a default configuration. Isolator switches are not meant to break current but rather to break a circuit when no current is passing through. If an attempt is made to open a switch when current is being carried, then severe arcing may occur at the switch contacts and could result in serious consequences including danger to the operator.

In the example embodiment numerous fields are shown including info, revision data, condition data, and configuration which are similar to in other screens and will not be described here in depth in order to save space. A rating field includes subfields for kV, Cont. Amp, BIL, and Momentary. An Equipment field includes a Tag number (#), Name, and Description. A Real-Time Data field includes sub-fields including Scanned status and control, each with Pins and control buttons allowing for opening/closing the isolator. In a dropdown list a Vertical Break, Horizontal two rotating post/center break, Horizontal break center rotating double break, and Extra HV column option may be included.

FIG. 11AD shows an example embodiment of a PTFE Neutral Section editor in accordance with the present invention. In the example embodiment a PTFE Neutral Section may include a set of switches in an open configuration. In many embodiments the PTFE neutral section may be added to OLV with the same or similar properties to a switch in an open position.

FIG. 11AE shows an example embodiment of a surge arrestor editor in accordance with the present invention. In an example embodiment a lighting arrestor may be added to OLV only and typically may be added only at a traction substation. In an example embodiment a lighting arrestor element may be added to an AC elements toolbar. Also, in an example embodiment a drop-down list with various subtypes including rod gap, sphere gap, horn gap, expulsion, impulse protective gap, electrolytic, lead oxide, pellet, thyrite, and valve may be added.

In the example embodiment as the train operates in constant acceleration mode and reaches 22 km/hr the operation mode is changed to constant power mode. Then, as the train passes 37 km/hr the train is operated in constant slip where traction effort may be inversely proportional to the square of the speed of the train in the constant slip section. After a cruising speed of 45 km/hr is reached the train operates in a coasting mode without applying input propulsion power. When the train approaches the destination station, electric regeneration braking is applied by operating induction motors as induction generators in order to convert the kinetic energy of the train into electricity to achieve energy conservation.

FIG. 17B shows another example embodiment of the figure shown in FIG. 17A. For illustrative purposes, a traction effort equation Fsubu=Wsubg=Wsubf+Wsubs+Wsubk+Wsuba(wsubg)(Gsubz)=(wsubf+wsubs+wsubk+wsuba) Gsubz where Fsubu is the traction at circumference of wheel in kgf, Wsubg is the total resistance to motion in kgf, Wsubk is the curve resistance in kgf, Wsubs is the gradient resistance in kgf, Wsuba is the acceleration resistance in kgf, Wsubf is the rolling resistance in kgf, WsubL is resistance to motion for locomotives in kgf, Wsub(WR) is resistance to motion for passenger trains in kgf, Wsub(WG) is resistance to motion for freight trains in kgf, Gsubz is train weight in Mgf, GsubW is weight of wagons in Mgf, csub0 is coefficient for rolling and frictional resistance of the axles in kgf/Mgf, and csub1 is coefficient for frictional resistance of the drive in kgf/Mgf.

Rolling Resistance (Wf) may be defined as Wsubf, =(wsubf)(Gsubz)=csub0Gsub1+(csub0+csub1)Gsubt+(csub2+(csub3)n)*0.5 A((V+15){circumflex over ( )}2)/10, where csub2 is the drag coefficient of the leading vehicle, csub3 is the drag coefficient of the following vehicle, csub4 is the drag coefficient of the following vehicle for freight trains, n is the number of following vehicles, A is the frontal area (geometric cross sectional area) of the vehicle in m{circumflex over ( )}2, V is the travelling speed in km/h, R is the curve radius in m, and a is the mean value of all fixed wheel bases with a<3.3S in m. Drag coefficients should be doubled for tunnel stretches.

FIGS. 17C-E show tables representing characteristic values of electric traction, force and velocity conditions for four operation regimes and train driving modes respectively.

Measurement of Train Resistance

The “Davis Equation” Ro=1.3+29/w+bV+(CAV{circumflex over ( )}2)/wn is the standard general formula for train resistance. Variables are defined as follows: Ro=resistance in pounds per ton, w=weight per axle (=W/n), W=weight of car, n=number of axles, b=experimental friction coefficient for flanges, shock, etc., A=cross-sectional area of vehicle, and C=drag coefficient based on the shape of the front of the train and other features affecting air turbulence, etc.

The Davis equation has been updated modernly to R=A+BV+CDV{circumflex over ( )}2. Variables are defined as follows: R=resistance in pounds, A=rolling resistance component independent of train speed (based on Journal resistance, Rolling resistance, Track resistance), B=coefficient used to define train resistance dependent on train speed (based on Flange friction, Flange impact, Rolling resistance wheel/rail, Wave action of the rail), C=streamlining coefficient used to define train resistance dependent on the square of the train speed (based on Head-end wind pressure, skin friction on the side of the train, rear drag, turbulence between cars, yaw angle of wind tunnels), D=aerodynamic coefficient or polynomial function used to further define train resistance (often combined with C) (based on Head-end wind pressure, skin friction on the side of the train, rear drag, turbulence between cars, yaw angle of wind tunnels), and V=train speed in miles per hour.

The equation which Davis proposed became R=1.3+29/W+0.045V+(0.0005aV{circumflex over ( )}2)/(WN) for freight cars. Another modified version of the Davis Formula which showed improved results in the 1940s and 1950s is: R=0.6+20/W+0.01V+(KV{circumflex over ( )}2)/(WN). Variables are defined as: R=resistance in pounds/ton, W=weight per axle in tons, N=number of axles, V=speed in miles per hour, K=combined air resistance coefficient (0.076 for conventional equipment, 0.16 for piggyback, 0.0935 for containers).

A Canadian National version of the train resistance formula is Rr=1.5+18N/W+0.03V+(CaV{circumflex over ( )}2)/(10000 W). Variables are defined as: Rr=the rolling resistance of vehicle in pounds/ton, N=number of axles, W=total weight in tons of locomotive or car, V=velocity of train in miles per hour, C=Canadian National streamlining coefficient, and a=cross-sectional area of the locomotive or car in square feet.

The chart in FIG. 17F shows an example embodiment of a train force (kN) vs. velocity (m/s) graph 17000. In the example embodiment line 17002 represents the load on the train motor while line 17004 represents the maximum load.

The tables in FIG. 17G, 17H show values of C coefficient for use with Canadian National Train Resistance Formulas. The tables depicted in FIGS. 17I, 17J show formulas for propulsion resistance for freight rollingstock and passenger rollingstock respectively.

Turning to FIG. 17K, an example diagram depicting the direction of forces used to calculated total vehicle resistance is shown. A generic formula for total resistance (Davis formula) R=AW+BV+CV{circumflex over ( )}2 includes A which varies with weight (such as journal or bearing resistance), B which varies with velocity (such as flange resistance) and C which varies with the square of velocity (such as air resistance). To elaborate: A=resistances that vary with axle load including bearing friction, rolling friction and track resistance; B) resistances that vary directly with speed such as flange friction and effects of sway and oscillation; and C) resistances that vary as the square of speed such as those affected by the aerodynamics of the train. W equals weight and V equals velocity in this formula as well.

Turning to FIG. 17L, a diagram depicting resistances affected by weight on wheels is shown. Journal resistance may be friction between the journal and bearing. Rolling friction may be friction between the wheel and rail due to “creepage” at the interface and can also include minute elastic deformation of wheel and rail surfaces. Track resistances may include deformation of track structure and consequent “uphill” running.

FIG. 17M shows an example graph of how resistances change with varying speeds on a conventional freight train and a diagram of a conventional freight train. FIG. 17N shows an example graph of how intermodal freight train resistance varies with different speeds and a diagram of an intermodal freight train.

A version of the Davis equation approved used by committee 16 of the American Railway Engineering Association (AREA) is Ru=0.6+20/w+0.01V+(KV{circumflex over ( )}2)/(wn) where Ru is the resistance in pounds/ton, w is the weight per axle (W/n), n is the number of axles, W is the total car weight on rails (tons), V is the speed in miles per hour and K is a drag coefficient. Values of K may be 0.07 for conventional equipment, 0.0935 for containers, and 0.16 for trailers on flatcars.

Additional terms for the Davis equation related to Gradient forces are RsubG(kN)=(Mg)/X where RsubG is the resistance (kN) due to gradients, M is the mass of the train in metric tons, g is the acceleration due to gravity (m/(s{circumflex over ( )}2)) and X is the gradient in the form I in X (for example a grade of three percent is expressed as X=I/0.03=33.33.

Additional terms for the Davis equation related to Resistance due to Curvature are rsubc((kN)/t)=0.01 k/(Rsubc) where rsubc is the resistance due to curvature (kN/ton), k is a dimensionless parameter depending on the train (typically varies from 500 to 1200), Rsubc is the curve radius in a horizontal plane in meters.

Application of the Davis equation to a high speed rail system (e.g. Japan Shinkansen Series 200) has shown the equation R=8.202+0.10656V+0.01193V{circumflex over ( )}2 where R is the total resistance (kN), V is the speed of the train in m/s. Tractive effort curve for the Shinkansen Series 200 can be derived from knowledge of the shaft horsepower delivered by the rail engines. The Shinkansen Series 200 typically deliver 15,900 horsepower.

FIG. 17O shows an example of coding which can be used in Matlab to calculate resistance forces for a Shinkansen Series 200 train. FIG. 17P shows an example of coding which can be used to calculate tractive effort of a Shinkansen Series 200 train.

A fundamental equation to convert power to tractive force (or effort) is shown as P=VT/η where P is the power output delivered by the engine, T is the tractive force or effort, η is the efficiency in converting power output to tractive force and V is the velocity of the vehicle. Tractive force or effort in typical units can be represented as T=2650(ηP)/V where T is in Newtons, P is in horsepower, and V is in kilometers/hour.

FIG. 17Q shows an example of a resistance/tractive effort in kN vs. speed in m/s graph. According to plots of resistance and tractive force versus speed, a high speed rail system will reach maximum velocity at 82.8 meters per second (298 km/hr) when the value of efficiency is conservatively assumed to be 0.70 and there is zero gradient.

Turning to FIG. 21, an example embodiment of traction editing tools are shown. In the example embodiment users can select from pointer tool, track layer tool, and others including train station and substation.

Stations are graphical polygonal objects, and in some embodiments, may be similar in nature to substations regarding their graphical properties and capabilities. Stations can be drawn in the program intersecting any track object. Stations default as rectangular shapes when placed on tracks but may be editable to change size or shape or may have different default shapes in different embodiments.

Turning to FIG. 22A, an example embodiment of a graphical view 22100 polygonal station 22010 is shown intersecting tracks 22012. A user may edit station 22010 characteristics by selecting station 22010 and bringing up editor 22200 as shown in FIG. 22B.

Turning to FIG. 22B, an example of station identification editor 22200 is shown. In the example embodiment a user may define station information, station element type, station condition, station type and name, and GIS coordinates. In the example embodiment station information includes a station ID, track section identification, and route lists that pass through the station. Route lists may auto-populate as may track section identification when a station is dropped on a track. In the example embodiment station element type includes radio buttons allowing the user to select signal, speed limit, level crossing, distance, and platform. Station condition allows users to select service conditions using radio buttons for in and out of service and also a drop-down menu for choosing the state of the condition, such as base. GIS coordinates fills in automatically when a station is dropped on a track. Included in the example embodiment are X, Y, Z coordinates, distance to nearest station, and nearest station name. Station type and name fields may include a graphical representation of the station such as a rectangle shown in the example embodiment. Station type may include a drop down menu with premade station types such as CST in the example embodiment. Users may be able to select platforms on one or both sides of a station in some embodiments and number the platforms such as 1 and 2.

Turning to FIG. 23A, an example embodiment of a graphical view of platform 23002 is shown. Platform 23002 s are polygon objects and have similar graphical properties and capabilities to substations. In some embodiments, platform 23002 s may be rectangular. In some embodiments, users may alter platform 23002 dimensions such as length and width and/or add bend points to convert platform 23002 into a polygon of different dimensions than rectangular. Platform 23002 s are prevented from intersecting tracks and in some embodiments will automatically rotate when moved along tracks. This ensures that the edge of platform 23002 nearest tracks is parallel to tracks. In instances where platform 23002 s are within or intersecting station 23004 boundaries then the program may automatically assign the platform to the station 23004 name. In instances where platform 23002 is moved outside station 23004 boundaries after starting within or intersection station 23004 boundaries then it may maintain station 23004 s name. In instances where platform 23002 is moved from within or intersecting station 23004 to a position within or intersecting a second station (not pictured), platform 23002 may automatically be assigned the name of the second station (not pictured). In instances where platform 23002 is initially placed outside any station boundaries then the platform 23002 name will be set as the station name.

Turning to FIG. 23B, an example embodiment of how platform 23002 may be moved along a track from the position shown in FIG. 23A is shown. In many embodiments, platforms may be selected and bring up platform editors such as in FIG. 23C.

Turning to FIG. 23C, an example embodiment of a platform editor 23100 is shown. In the example embodiment a platform information section includes a platform identification, a track section identification and a route list. In some embodiments the platform identification is a display only field that shows the assigned station name. A platform condition section includes radio buttons indicating whether the platform is in or out of service and the state of the platform (such as base). A GIS coordinates section includes X, Y and Z coordinates of the platform. Additionally, a platform list may be included with a train station dropdown selection list.

In some embodiments there may be additional fields such as indicating which side of the platform has tracks along its edge. In such embodiments a side ‘A’ may represent the left side of the platform and a side ‘B’ may represent the right side of the platform regardless of the platform orientation. In some instances, if platform A & B sides are selected then there may be active side indicators on each side of the platform as shown in FIG. 23E.

Turning to FIG. 23D, an example embodiment of platform 23002 is shown with one active side 23006.

Turning to FIG. 23E, an example embodiment of platform 23002 is shown with two active sides 23006 and 23008. These two active sides may appear after a user has indicated in a platform editor that both sides are active in some embodiments. In other embodiments two active sides may appear when a platform is placed in an orientation in GIS with tracks along both sides of the platform.

Route and Track Definitions in some embodiments is a five step process. In embodiments where it is a five step process the steps may include: step 1) placing platform and/or station markers on GIS; step 2) creating tracks on GIS between stations using combinations of track segments; step 3) defining routes by designating start stations and end stations; step 4) defining train information; step 5) assigning trains to routes and trips (where routes are endpoint to endpoint non-time specific and trips are time-specific).

Turning to FIG. 24A, an example embodiment of step 1) placing platform and/or station markers on GIS 24000 is shown. In the example embodiment a user may place station 24002. After placing station 24002 the user may place platform 24004 and connection point 24006. Next a user may place station 24008. After placing station 24008 the user may place platform 24010 and connection point 24012. The user may then place platform 24014 and connection point 24016.

Turning to FIG. 24B, an example embodiment of step 2) creating tracks on GIS between stations using combinations of track segments 24100 is shown. In the example embodiment markers and nodes may create track segments. Platforms such as platform 24004, platform 24008, and platform 24010 may be markers placed on top of automatically created nodes. In some embodiments a user may double-click or otherwise select a track segment to launch a track editor. Track segments are considered the segments of track between markers. The track editor may be a modeless editor in some embodiments. After launching the track editor, the program may enter a track group definition mode that allows the user to select multiple track segments. This operability may be similar to standard OLV logic in that selecting multiple track segments may be accomplished by using a connected and operable mouse or cursor keys. When a track segment is selected, and the track editor is open, the program may automatically select all connected segments using an “automatic walk” until a node is encountered. After encountering a node, the user may choose the next path. In many embodiments using a mouse to click once on a segment will select the segment while clicking on the segment again will unselect the segment. In some embodiments the program may automatically select a connecting segment if the user skips a connected segment. Using this multi-select functionality to include all track segments is important in many embodiments in order to ensure that all connected tracks are consistent in their definitions and functionality.

Turning to FIG. 24C, step 3) defining routes by designating start stations and end stations 24200 is shown. In the example embodiment multiple track segments may be selected including track segment 24020, 24022, 24024, 24026.

Turning to FIG. 24D, an example embodiment of how track segments may be automatically selected is shown. In the example embodiment a first step includes selecting track segment 24026. This will trigger a second step of automatically “walking up” to the first node and selecting track segment 24024. Then a third step is to automatically walk up to the next node and selecting track segment 24022. In a typical embodiment, the selection process is stopped, and the track group definition is complete when a platform and/or station is encountered. After a platform and/or station is encountered a new track group may be started by clicking on a “new” button as shown in FIG. 24E.

Turning to FIG. 24E, an example embodiment of a track editing window of a user interface is shown. Included is a track list with a breakdown of tracks by station segments. Also included is Track Segment Information. This Track Segment Information includes information such as object names, object types, segment identification by end-points, segment length, distance, speed information including class and unit, GIS coordinates including X/Y/Z coordinates and grade, and bend radius information. Track Segment Information may include all elements between two stations. Standard filters may be added to each column. Also included is a route listing. The route listing may be a read-only description of routes that are defined for the selected track. Track assignment may be done in the route editor. Also included is a rail resistance portion which allows users to select a track warehouse which may be a database of common track information.

In the example embodiment the dialog is modeless and when any item is selected the program may automatically zoom in order to find the element on the active presentation in GIS or OLV. The selected item may also be colored with a “selected color” choice button from a theme manager.

By selecting a tree item “Track 1” the user may change the name of the tree item by right clicking using an attached mouse and clicking edit. This provides for in-line editing of the name. In some embodiments there is no need for an edit dialog box. Regarding rail resistance, when any track with the tree item “Track 1” name is selected in the tree then the rail resistance warehouse selection may be displayed. Once a warehouse is selected by the user, the warehouse ID is assigned to all track segments incorporated in that particular track (“Track 1” in the example embodiment).

Turning to FIG. 24F, the table shown in FIG. 24E may be simplified when bend markers are considered.

Pages in the editor may be labeled train schedule or timetable, train configuration, train assignment, route, track, and others.

Turning to FIG. 25A, an example embodiment of a train and consist editor 25000 is shown. Typically, this train and consist editor 25000 will be launched from a study toolbar (as shown in FIG. 37, third button down, although numerous other placements exist in other embodiments). Train and consist editor 25000 includes a Rolling Stock/Train Name portion with a list of train names, a locomotive section which has a library button, and a coupled consist section which has a library button. Located next to the train listing is a check box for each selection in the list which disables the selected train from being available in a Timetable or Schedule editor. If the train was previously selected in the timetable editor and the check box is unchecked, then the train is inactive in the timetable used to run the analysis.

Additionally, a user may manipulate subfields including start time, simulation days, and stop time in a total simulation time field. Similarly, a playback time field may include subfields including start time, simulation day and stop time. Also included are play, pause, stop, rewind/reset, fast forward, step rewind and step fast forward buttons for controlling playback. A menu list may be provided that expands to a list similar to transient stability.

Turning to FIG. 40A, an example embodiment of a train animation/dispatch animation is shown. This screen may be displayed when a play button is pressed in the traction power time slider screen shown in FIG. 39. In the example embodiment train operation animation may be shown in GIS view and OLV.

Turning to FIG. 40B, an example embodiment of a train animation selection menu with radio buttons is shown such that a user may select different train symbols for display in an animation in addition to three options for display although many more options may be available. Users may also be able to change playback rate which is the plot time step as defined in the study case. Resulting annotation and train location will align to the same step when this is selected. In an example embodiment a playback rate equation representation may be Playback rate=X*plot time step defined in the study case where a default is 0.50 seconds. Default is typically the calculation time step which is the plot time step. X is typically a factor and the playback rate is the result of multiplying X and the plot time. This can allow for faster playback or slower playback, as required by a user.

Turning to FIG. 40C, an example embodiment of logic related to Train Symbol 2 from FIG. 40B is shown. In the example embodiment a number of rectangles may equal the number of cars in a consist to be represented based on the train configuration. Colors of rectangles may be used to represent whether a traction motor is present. For example, an orange rectangle may be used to represent a traction motor presence while a blue rectangle may be used to represent no traction motor presence. The length of shapes may be proportional to the total length of the train configuration as well. Trains can be made to scale in various embodiments and train names can be shown to identify trains in various embodiments.

Turning to FIGS. 40D-40E, an example embodiment of an animation diagram is shown. In the example embodiment, when an animation trigger is selected, and a user selects a specific train, for instance by clicking it, the diagram may automatically be moved to the center of a display screen. When the diagram has moved such that the train is in the center of the screen, the diagram may move such that a calculated train location is always in the center of the screen. This will give a user the impression that the train is stationary while the rest of the map or OLV moves in relation to the train.

Turning to FIG. 41A, an example embodiment of an OLV Display Options edit toolbar is shown. In the example embodiment a display options-train window is shown which allows users to change AC, AC-DC, Train, and Colors options. In the example embodiment a group named traction is displayed and a display options matrix as shown in FIG. 41B may be displayed.

Turning to FIG. 41B, an example of a display options matrix is shown. In the example embodiment an “X” may hold the place of a checkbox and allow users to turn display of the selected option on or off. In the example embodiment a blank spot or a “-” implies that no checkbox is required for the function. In the example embodiment station, platform, autotransformer and booster transformer have options for rating, kV, A, Phase, Z, and DB as shown. Track node, Track-OCS, Track-Rail have options for WH ID, kV, length, phase, Z, and DB as shown. Insulator with Isolator, section insulator, insulated overlap, and isolator switch have options for rating, kV, A, open, Z, and DB as shown. Speed limit, signal, level crossing, distance, elevation, and bend radius, have options for nearest station distance, elevation, value 1, value 2, status, and DB as shown. In speed limit, value 1 may be passenger speed while value 2 may be freight speed. In signal, value 1 may be number of lights, value 2 may be type, and status may be configuration status.

Turning to FIG. 41C, an example embodiment of a study toolbar as shown in OLV is shown. In the example embodiment a study toolbar in OLV may include a results page, an AC page, an AC-DC page, and a colors page which may each be the same as unbalanced load flow. A train page may be the same as an edit toolbar described above. Included are fields for SRS ID, field name, light/heavy/NA, display only, format, range, display format, and default English and metric units with subfields for value and unit.

Turning to FIG. 41D, an example embodiment of a Display Options—Traction Power window is shown. In the example embodiment a results page may include information such as a Voltage Unit (e.g. kV) selection, show units and check-all selection boxes, voltage field, power rows field, load term, Base kV field, voltage drop field, average/phases field, flow results field, branch losses field, and meters field. The voltage field may include check boxes for bus mag., bus angle and load term mag. and load term mag may have radio buttons for L-N and L-L. Power rows field may have drop down units and radio buttons for kW+jkvar, kVA, and Amp. Load term, base kV field may have radio buttons for load rated kV and Bus Nom. kV. Voltage drop field may have check boxes for Line/Cable, Train and Load FDR. Average/Phases field may have radio buttons for Average values, All phases and All sequences. Row results field may have check boxes for branch, source, load, composite motor and composite network. Branch losses field may have a check box for kW+jkvar. Meters field may have check boxes for Ammeter, Voltmeter and Multi-Meter.

If the check box for train in the Voltage drop field is checked then a power flow annotations for Train may be displayed based on a “power flow” selection. A field called train may also be added to a Results page as shown in FIG. 41E. Trip data may be displayed for each train based on selections in the train field on the Results page. The train field in the example embodiment shown in FIG. 41E includes radio buttons for route, train and resistance. Check boxes may include speed, location/distance, elevation, kWh, Tractive effort, net acceleration, acceleration, rolling and curve.

It should be noted that all features, elements, components, functions, and steps described with respect to any embodiment provided herein are intended to be freely combinable and substitutable with those from any other embodiment. If a certain feature, element, component, function, or step is described with respect to only one embodiment, then it should be understood that that feature, element, component, function, or step can be used with every other embodiment described herein unless explicitly stated otherwise. This paragraph therefore serves as antecedent basis and written support for the introduction of claims, at any time, that combine features, elements, components, functions, and steps from different embodiments, or that substitute features, elements, components, functions, and steps from one embodiment with those of another, even if the following description does not explicitly state, in a particular instance, that such combinations or substitutions are possible. It is explicitly acknowledged that express recitation of every possible combination and substitution is overly burdensome, especially given that the permissibility of each and every such combination and substitution will be readily recognized by those of ordinary skill in the art.

In many instances, entities are described herein as being coupled to other entities. It should be understood that the terms “coupled” and “connected” (or any of their forms) are used interchangeably herein and, in both cases, are generic to the direct coupling of two entities (without any non-negligible (e.g., parasitic) intervening entities) and the indirect coupling of two entities (with one or more non-negligible intervening entities). Where entities are shown as being directly coupled together or described as coupled together without description of any intervening entity, it should be understood that those entities can be indirectly coupled together as well unless the context clearly dictates otherwise.

While the embodiments are susceptible to various modifications and alternative forms, specific examples thereof have been shown in the drawings and are herein described in detail. It should be understood, however, that these embodiments are not to be limited to the particular form disclosed, but to the contrary, these embodiments are to cover all modifications, equivalents, and alternatives falling within the spirit of the disclosure. Furthermore, any features, functions, steps, or elements of the embodiments may be recited in or added to the claims, as well as negative limitations that define the inventive scope of the claims by features, functions, steps, or elements that are not within that scope.
